That specific curative reputation, focused on a single ailment rather than the broader blessings attributed to many such sites, gives it a particular character, even if the crowds who once came here are long gone.

The well itself is an unusual shape: a D-plan enclosure roughly 3.5 metres north to south and 2 metres east to west, bounded on three sides by a stone wall up to 1.75 metres high and half a metre thick, and on the eastern side by a natural cliff face that substitutes for a built wall altogether. By the time the local antiquarian Grove White documented it somewhere between 1905 and 1925, it was already overgrown and abandoned, though he recorded that it had formerly been much frequented for the cure of sore eyes. He also noted its name from the Ordnance Survey Field Book of 1840: Tubbercooragh a Glynna, a name rooted in the Irish for well, tobar, and suggesting a connection to a glen or valley. Holy wells, of which Ireland has thousands, were typically sites of pattern days, communal gatherings combining prayer, ritual circumambulation, and social activity; the specific therapeutic traditions attached to individual wells, like this one's association with eyesight, often drew pilgrims from considerable distances. That the well at Lisleagh had already fallen out of use by the early twentieth century suggests its active life as a place of pilgrimage may have faded during the nineteenth century, perhaps as older devotional practices declined across rural Ireland.
